Disability at Work: A Look Back and Forward

Abstract

Purpose This article presents new evidence on employment barriers and workplace disparities facing employees with disabilities, linking the disparities to employee attitudes. Methods Analyses use the 2006 General Social Survey to connect disability to workplace disparities and attitudes in a structural equation model. Results Compared to employees without disabilities, those with disabilities report: lower pay levels, job security, and flexibility; more negative treatment by management; and, lower job satisfaction but similar organizational commitment and turnover intention. The lower satisfaction is mediated by lower job security, less job flexibility, and more negative views of management and co-worker relations. Conclusion Prior research and the present findings show that people with disabilities experience employment disparities that limit their income, security, and overall quality of work life. Technology plays an increasingly important role in decreasing employment disparities. However, there also should be increased targeted efforts by government, employers, insurers, occupational rehabilitation providers, and disability groups to address workplace barriers faced by employees with disabilities, and by those with disabilities seeking to return to work.

Notes

  1. Analysis of the 2014 American Community Survey shows that among working-age people who did not receive any disability income in the past 12 months, 49.7% of people with disabilities were employed compared to 76.9% of people without disabilities (calculations available on request).

  2. It is likely these figures understate the problem due to “social desirability” bias, and the frequent discrepancy found between the attitudes employers express towards people with disabilities on surveys and their actual hiring practices [71].

  3. Ordered probits predicting the ease of finding another job found the disability coefficients of -0.160 (T = − 1.129) before controlling for occupation, and − 0.170 (T = − 1.170) after controlling for occupation. Both regressions control for gender, race, age, Hispanic, and education. The sample sizes were 689 and 684 respectively. Full results are available on request.

Outside Opportunities

Ease of finding other job “How easy would it be for you to find a job with another employer with approximately the same income and fringe benefits as you have now?” (Very easy 3/Somewhat easy 2/Not easy at all 1)(mean = 1.97, SD = .78).

Appendix 2: Testing of Structural Equation Model

To test the model in Fig. 1 and evaluate how the disparities are related, we employ a structural equation model using the random sample that answered questions in the QWL module. The model is restricted to respondents with valid observations on every measure, and uses all of the measures except for organizational commitment, since the QWL module did not contain an adequate measure of this. The analysis is performed with Lisrel 8.7 statistical software [83]. Structural equation models are typically based on multi-item measures of latent variables. As our measures have several single indicators, we correct for the reliability of the single-item indicators of latent variables following Anderson and Gerbing’s method, which assigns a unique variance of 0.95 to these variables and sets the residual error variance for these variables to the product of variance of the indicators multiplied by 0.1 [84].

Variable means and correlations, excluding the control variables, are presented in “Table 5 (Appendix 3)”. To evaluate the factor structures of the data, we employ a two-step approach to the structural equation model [54]. Absolute fit indexes show that the measurement model provides an acceptable fit to the data (\(\chi\) 2 = 1097.26, df = 397, p < .0001, TLI = 0.94, GFI = 0.92, CFI = 0.96, NFI = 0.94, RMSEA = 0.050). Our hypothesized model presented in Fig. 1 provides an acceptable fit to the data (\(\chi\) 2 = 1963.63, df = 527, p < .0001, TLI = 0.88, GFI = 0.88, CFI = 0.93, NFI = 0.91, RMSEA = 0.063). To confirm whether our model has the best fit to the data, we conduct the chi-squares difference procedure [85].

In this procedure, we develop seven alternative models according to the extant literature, and then compare the chi-squares and degrees of freedom between our hypothesized model and each of seven alternative models. As seen in “Table 6 (Appendix 3)”, the goodness of fit index of each alternative model is acceptable except for alternative model 5, which has an unacceptable Root Mean Square Error of Approximation (RMSEA) of 0.081. Thus, six alternative models (i.e., alternative models 1, 2, 3, 4, 6, and 7) are employed for chi-squares comparison.

The results show that the chi-squares differences between our hypothesized model and each of the alternative models 2 to 7 are significant. The model that has more parameters and fewer degrees of freedom is favored when the chi-squares difference is significant [85]. Our hypothesized model is therefore preferred to alternative models 2–7, which have higher chi-squares with fewer parameters and more degrees of freedom than our hypothesized model. In the chi-squares comparison with alternative model 1 that has a smaller Chi square and fewer degrees of freedom than our hypothesized model, the result shows that there is no significant difference in the chi-squares between the two models (∆\(\chi\) 2 = 3.11, ∆df = 3). In this case, the model that has fewer parameters is favored [85]. Hence, our hypothesized model, which is more parsimonious than alternative model 1, is preferred.
